How these dates were made

Why this bar's edges are floors, not a founding and a fall.

The atlas draws the world at 5 moments in time, not continuously. This bar runs from the first snapshot in which Celtic kingdoms appears to the last, so both edges are floors — the earliest and latest years it is attested, not a founding and a dissolution.
